The AirTAC GFR600C25LF1WT AirTAC Filter Regulator 1 in NPT is a genuine G-series filter regulator: water separation, 40 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has See datasheet ports, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The AirTAC GFR600 series is a filter regulator: one body that removes water and particulate from compressed air and reduces the pressure supplied downstream. This GFR600C25LF1WT is the size 600 unit with a 1 in NPT port, the low-pressure regulator type, a 5 um filter element (the 40 um element is the standard alternative), a differential-pressure drain, and the embedded square gauge reading in MPa. The size 600 bowl is aluminium alloy, maximum inlet pressure is 1.0 MPa (145 psi), and the operating range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR filter regulator family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, PT as the standard thread and G or NPT as order options, plus a choice of drain type, filter grade, gauge and scale, and standard or low-pressure regulator type. Flow is published as curves rather than a single rating, so ask us to confirm the figures for your application before ordering.

Specifications follow the official AirTAC G-series air-preparation data. The regulating band is set by the drain type: automatic and differential-pressure drains regulate 0.15 - 0.9 MPa, a manual drain regulates 0.05 - 0.9 MPa. Standard type, regulating 0.15 - 0.9 MPa (20 - 130 psi). Air must not freeze in the unit. Flow curves, weight and outline dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.

Field order is size, port, drain, type, bracket, gauge, shape, scale, grade, thread, reflux — a blank position takes the default. Example: GFR300-08 is a 300 body, PT1/4", differential drain, standard type, bracket included, gauge fitted, 40 µm, PT thread, no reflux valve.
A larger body carries a larger port and holds set pressure better as flow rises. AirTAC publishes flow only as curves, so size the body from your peak demand with headroom. The GFR600 uses an aluminium-alloy bowl; the 200, 300 and 400 bodies use PC.

Conditioning the main compressed-air feed that serves mould cooling and forming circuits on a glass container line, where the low-pressure regulator type holds the circuit at a reduced setting and the 5 um element keeps water and particulate out of the forming equipment.
Filtering and regulating the supply to pneumatically actuated valves on weaving looms, where the 1 in NPT port matches the mill's main air headers, the low-pressure type suits reduced-pressure circuits, and the MPa gauge gives operators a clear setpoint reference.
Supplying the filtered, reduced-pressure air that carries PET bottles along air-cushion conveyors on a bottling line, where the 5 um element protects the conveyor's air channels and the differential-pressure drain clears accumulated water without interrupting the line.
Pick the size and port for the air your line actually uses - this unit is the top of the range at size 600 with a 1 in NPT port. The L code selects the low-pressure regulator type, intended where downstream pressure must sit below the standard range; the exact adjustment range of the low-pressure type is not published in the catalogue, so confirm it with us. The 5 um element (code W) suits air feeding sensitive components, while the 40 um standard element is the usual choice for general supply. Drain options are differential-pressure (fitted here), automatic or manual, and the square gauge reads in MPa - psi or bar scales and an external round gauge are alternatives. Thread is NPT on this unit; PT is the standard and G is also available. A mounting bracket is included. Flow is published as curves, not a single rated figure, so send us your application and we will confirm sizing against the datasheet before you order.
Quick checklist
The aluminium-alloy bowl on the GFR600 suits harsher environments than a PC bowl. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR600 as curves, not as a single rated figure, so there is no one honest number to quote here. Tell us your inlet pressure, required set pressure and expected air demand, and we will read the datasheet curves and confirm the sizing with you before you order.
The L code selects the low-pressure regulator type, used where downstream pressure must sit below the standard range; its exact adjustment range is not published, so confirm it with us. The W code sets the 5 um filter element instead of the 40 um standard. This unit otherwise carries a 1 in NPT port, differential-pressure drain, embedded square gauge in MPa, aluminium alloy bowl, included bracket, 1.0 MPa (145 psi) maximum inlet and a -5 to 70 C operating range.
